Vassilis Serasidis / VS1053

A simple library for decoding MP3 files with the VS1053 CoDec chip. The initial library was written by Kaoru Onoe. The library is patched to work with some "LC Technology" VS1053 board that have some IC pins disconnected. Because of that problem, there was no sound out of that boards. Now, these board work ok !
